“…The installed capacity of this company is based on the annual production of 94,000 tons of coniferous pulp and the processing of 50,000 tons of waste paper into 136,000 tons of various types of packaging paper. A part of the paper is used for own production of corrugated cardboard, cardboard and paper packaging [11]. In the mentioned process, technological wastewater from pulp production, technological wastewater from paper production and sanitary wastewater are generated.…”

“…Today, it is the most widespread biological process for wastewater treatment. Microorganisms, mainly bacteria, protozoa and metozoa, are found on gelatinous flakes of sludge in the aeration pool, where with the help of oxygen, a concentration of 2 mg/l is sufficient for the process, in the process of microorganism metabolism, the decomposition of the substrate is ensured [11]. Excess biological sludge is transported to the thickener, where it is mixed with the help of a grate mixer.…”

The object of research in this scientific paper is the treatment of waste generated by paper production in industrial landfills. In the part of the paper production process, i.e. in its subsystem for wastewater treatment, a significant amount of solid waste is generated, which ends up in industrial landfills. The reason for the impossibility of returning to the production process lies in the fact that the sludge contains larger amounts of moisture and present chemical components that are isolated in the paper production process or during wastewater treatment. In the experimental part of the paper, a “trial plot” was selected on which seedlings of the paulownia elongate plant were planted in the waste sludge. The process of plant growth was monitored for two years and bioremediation, i.e. transfer of elements from sediments to plants, was analysed by modern instrumental methods. Based on the results obtained by research, it can be said with certainty that Paulownia elongate can be used in bioremediation of areas where these sediments are deposited.

“…The share of MgO in the slag is increased compared to the allowed 5%. A higher quantity of MgO can affect in addition to volume instability, the appearance of cracks [56] in mixtures with cement, which demands special attention in experimental work. The measured slag pH value is 8.…”

Reducing the costs of repairing concrete structures damaged due to the appearance of cracks and reducing the number of people involved in the process of their repair is the subject of a multitude of experimental studies. Special emphasis should be placed on research involving industrial by-products, the disposal of which has a negative environmental impact, as is the case in the research presented in this paper. The basic idea was to prepare a mortar with added granulated blast furnace slag from Smederevo Steel Mill and then treat artificialy produced cracks with a Sporosarcina pasteurii DSM 33 suspension under the conditions of sterile demineralized and water from Danube river in order to simulate natural conditions. The results show a bio-stimulated healing efficiency of 32.02% in sterile demineralized water and 42.74% in Danube water already after 14 days. The SEM images clearly show calcium carbonate crystals as the main compound that has started to fill the crack, and the crystals are much more developed under the Danube water conditions. As a special type of research, microscopic images of cracks were classified into those with and without the presence of bacterial culture. By applying convolutional neural networks (ResNet 50), the classification success rate was 91.55%.

“…Pollutants represented in the composition of leachate of municipal landfills can be divided into four groups: soluble organic components, inorganic macrocomponents, heavy metals and xenobiotic organic components (Kjeldsen et al, 2002;Renou et al, 2008;Abbas et al, 2009;Bušatlić et al, 2017). Except for the mentioned four groups of components, other compounds and elements such as borate, sulphide, selenate, barium, lithium, mercury and cobalt (Kjeldsen et al, 2002) can also be identified within chemical composition of leachate.…”
